The Cerwin-Vega CVi-218S (Contra-Sub) is a portable, dual eighteen-inch dedicated subwoofer system designed to extend and supplement the low frequency extension of CVi full range systems in live music and playback applications.

The CVi-218S features two high power, cast frame eighteen inch transducers with 3 inch voice coils for extended use during high SPL applications. Steel handles and pole mount cup are also featured for use as a base for pole mounted full range systems. This configuration allows the two drivers to work together in the same acoustic space to reduce distortion components caused by driver mechanical non-linearity when the system is driven at high levels. The result is cleaner, smoother low frequency reinforcement at higher SPL levels.
